Spurs' Tony Parker (9) goes up for a shot against the Grizzlies defense during the first half in Game 2 of the Western Conference finals NBA basketball playoff series, Tuesday, May 21, 2013, in San Antonio.

SAN ANTONIO — San Antonio Spurs point guard Tony Parker plans to have an MRI on Thursday on his troublesome left calf, although he doesn't expect to miss any playing time in the Western Conference finals.

Parker says the MRI is "just to make sure" he's improving on schedule from the injury, which limited his effectiveness in the final two games of the Spurs' second-round series against Golden State.
